HARRY C. KRENTLER, OF INDIANAPOLIS, INDIANA.

SPECIFIGATION forming part of Letters Patent No. 795,227, dated J uly 18, 1905.

Application filed January 28, 1905. Serial No. 243,160.

To all whom it may concern.-

Be it known that I, HARRY O. KRENTLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Devices for Cleaning Stovepipes or other Articles, of which the following is a specification.

This invention relates to improvements in appliances for cleaning the soot out of stovepipes and stovepipe-elbows and for cleaning other pipes and all other articles for which it may be applicable; and the object of the invention is to provide an eflicient device that will adjust itself to variations in the size and shape of the pipe to be cleanedas, for example, where the pipe is partially flattened and out of round, as often happens.

The object also is to provide a simple and inexpensive article that will be light and durable as well as effective in its operations.

I accomplish the objects of my invention by the mechanism illustrated in the accom panying drawin s, in which Figure 1 is a detail in longitudinal section of a portion of a joint of stovepipe with my invention in operative position inside of said stovepipe. Fi 2 is a cross-section of the stovepipe on the dotted line 2 2 of Fig. 1 looking in the direction of the arrows and showing my cleaning device in operative position in said pipe, and Fig. 3 is a view of a modified form of cleaner having a wooden handle instead of a handle formed out of the wire from which the body of the cleaner is made.

Like characters of reference indicate like parts tlnoughout the several views of the portion will be bent in the form of a circle as near as practicable and will extend over more than half of a circle, as shown in Figs. 1 and 2. By this construction the scraper part 10 will be unsupported between the angular bends at the junction of part 10 with the sides of the loop 6. This construction permits of a contraction of the diameter of the circular scraper portion 10 to allow the device to be inserted within the section of stovepipe, after which by the elasticity of the wire the device will spring outwardly, so as to cause the scraper to bear with a scraping fit against the inner walls of the stovepipe. Then by drawing the device back and forth longitudinally through the pipe by taking hold of same at its handle 8 the soot and adhering foreign matter within the pipe will be thoroughly loosened, so as to be readily emptied out by raising the pipe into a vertical position.

The making of the scraper 10 in the arc of a circle greater than a half-circle is an important feature of myinvention, as the extension past the diameter provides portions that prevent the scraper from bearing at diametrically opposite points of the i e at the bends between the scraper sides oi the loop without touching at intermediate points between said diametrical pipe portions.

In the modification shown in Fig. 3 the ends of the loop are passed through awooden handle 11, and the latter is retained by turning the ends of the wires over against the ends of the handle, or the handle may be secured in any other suitable manner.

Having thus fully described my invention, what I claim as new, and Wish to secure by Letters Patent of the United States, is-

1. In a device for cleaning stovepipes and other articles, a wire bent at its middle to form a loop, the sides of said loop being crossed at one end of the loop and the crossed wires twisted together and extended beyond said twist to form a handle, the end of said loop opposite the handle being bent at ap- "formed in the arc of a circle greater than a proximately right angles to the sides of the loop to form a scraper.

2. In a scraper for cleaning stovepipes and other articles a wire bent into a loop and having its sides crossed and twisted together, a handle at the twisted end of said loop, said loop having its end opposite the handle bent approximately at right angles to the sides of 1c the loop to form a scraper, said scraper being semicircle.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 14th day of January, A. D. 1905.

HARRY C. KRENTLER.
